More isn't always better: Too much calcium has risks. Dietary calcium is generally safe, but more isn't necessarily better, and excessive calcium doesn't provide extra bone protection. If you take calcium supplements and eat calcium-fortified foods, you may be getting more calcium than you realize.
Genetic Recombination in Bacteria. This is a process where genetic materials, contained in two separate genomes, are brought together within one unit. In bacteria the recombination takes place by (1) transformation, (2) transduction and (3) conjugation.
The three main types of asexual reproduction are (Binary/Multiple)  Fission, Budding, and Fragmentation. Each type is used in different  ways for different organisms.ach of the new offspring then grows to a normal size. Binary fission is the usual method of reproduction of one-celled organisms including protozoa, bacteria, and many algae. Binary fission is also the process by which multi-cellular organisms grow. Budding is another type of asexual reproduction.
